Importance of union in 'C':unions are the concept borrowed from structures in structures we allow different datatypes in which each datatype is allocated a separate memory location .But in unions same as structures we use different data types but all the datatypes will be allocated to a single memory location and only one datatype with maximum size will be used for allocation of all the data types used in a union program.Sample code for union is as follows:union item {int m;float c;char x;}code;In the above program we used three kinds of datatypes here integer size is 4 so the other data types will be shared in the same location of size 4.then the memory will not be wasted and all the memory will be utilized perfectly.

Static allocations are allocated upon the stack, which has limited space. Dynamic allocations occur at runtime and are allocated on the heap, which is "virtually" unlimited (32-bit systems can only address 4GB of memory, at most, but 64-bit systems are only limited by available disk space). Thus the stack should be used for small data structures and local data that are used often in your code, but are fixed in size. The heap should be used for larger, more general purpose allocations or when the size of the structure is variable.
Turbo C variables are memory place holders for storage of data during the execution of a Turbo C program. Types of variables include integer, real and char.

Different types of oranges, different soils, and different ripeness can cause changes in the amounts of vitamin C.
There is no memory management operator in C++ -- it is an unmanaged language. You use the C++ new operator to allocate memory, and use the C++ delete operator to release previously allocated memory.
